I just bought all the parts to a new system. This is my first time ever builiding a system from scratch. It is now time for me to install the heatsink/fan. I bought a cooler master Ep5-6I11. I have tried a couple of times to put it on the cpu, but it seems like i'm pushing to hard to secure the second clip. Is there supposed to be alot of force involved in installing it. I feel like i'm either gonna break the CPU or the mother board. Oh yeah it's an Athlon 1.2GHz ( If you wanna check out the rest of the stats then click on My rigs)
